摘要：

Polyaniline films doped with camphor sulfonic acid have been studied for electrical resistivity in the temperature range 77-353 K under different thermal conditions. Thermal annealing is found to increase the resistivity and also its temperature dependence. The temperature above which the resistivity exhibits metallic characteristics is shown to depend very sensitively on the presence of moisture. We use the inhomogeneously-disordered-metal model to interpret our resistivity results.
